World Diabetes Day 2017: All you need to know about blood glucose test

HIGHLIGHTS

Diabetes mellitus is diagnosed based on a high level of glucose in blood

Insulin regulates the blood glucose (sugar) levels

Why is a blood sugar test done?

A blood sugar test is done for the diagnosis of diabetes. This is because diabetes mellitus is diagnosed on the basis of high blood sugar levels. Three tests, the blood glucose test, done fasting and 2 hours after breakfast are used for diagnosis.

Insulin does play a role here. When we eat, the body breaks food down into glucose (sugar) which it uses in the form of energy. What insulin does here is that it helps the cells to use this glucose in the form of energy and also allows it to store the same in the liver for using later. So insulin basically regulates blood glucose levels.

Diabetics, however, do not produce the required amount of insulin. As a result, the blood sugar level goes up leading to increased glucose levels in the bloody, known as hyperglycemia.
